摘要：

We investigate the energy scaling of high-order harmonics in Ar using a loosely focused beam under the phase-matched condition. By adjusting the argon gas density and the pump laser focusing condition, a total output harmonic energy as high as 0.7 muJ is obtained in the spectral region of 34.8 to 25.8 nm (the corresponding order of the 23rd to 31st harmonic), while the 27th order harmonic (29.6 nm) energy attained is as high as 0.33 muJ with almost perfect spatial profile. Both high efficiency and good spatial quality are achieved simultaneously.
